IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 47.465, dated April 25, 1865.

To ail whom it may concern:

Be it known that I, JAMES C. THOMAS, ot' Redpoint, county ot' Cecil, in the State ofM-aryland, have invented a new and Improved Machine for Planting Corn; and l do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon. 1

Figure l represents a longitudinal section ofthe planter, and Fig. 2 a transverse section oi' the same. l

To the wheel A is attached a three-forked seed-box, B, the distance between the arms of which is measured by one-third-of the circle. The center ot' this box is concentric with the wheel A. A hollow tooth, C, is so attached to the frame-work of the planter 'as to strike the ground directly beneath the axis of the wheel A andsufeiently near to the seed-box B to receive from it the seed every time an arm ofthe same. passes. rEhe seed is then thrown out of the seed-box B by means of a springslide, D, striking the bar E, attached to the frame ot' the planter. In front ot'Fig. 1 there is a tooth,G, beveled from the inside, intended to level the ground in front of said Fig. 1 as the same moves forward.

`Letter' H represents a easter-Wheel, with a perpendicular shaft, A. This wheel, H is used to elevate and depress the large wheel, Fig. l, t

thereby relieving these wheels from pressure on the ground as the planter' is turned in planti ing. This elevation or depression of said Fig.

1 is made by means of the toothed sector'B,

operated by means of a lever, C', and the long y rod D', the said toothed sector B working in the revolving rack A', as seen from the draw- ;ings in said shaft A".

What l claim as my invent1on,and desire to` secure by Letters Patent, is-

1. The forked seed-box B, in combination with the wheel Aand the hollow tooth C, when constructed substantially as andt'or the purpose specified.

2. 1 do not-claim the easter-wheel and revolving rack per se, these having been before,

used, but the circular rack A', sector l5. lever C, and arm D, when the severalparts are eon struoted and arrangedV substantially as and for the purpose herein set I'orth.
